To all whom t may concern:

Be it known that I, CHARLES FnNsliY, a citizen of the United States, andresident yo f the city of St. Louis, and State of Missouri, haveinvented certain new and useful Improvements in Audiphones, of which thefol` lowing is a specification, containing a full, clear, and exactdescription, reference being had to the accompanying drawings, forming apart thereof. l

My invention relates to improvements in audiphones and has for itsprimary object a device for improving the hearing which is soconstructed as to eliminate sudden inrushes or increasing pressure ofair to the interior of the ear.

A further object is to construct a device for improving the hearingwhich is adapted to be inserted in the ear and which is so arranged asto prevent dust and other foreign matter from entering and clogging thesame.

In the drawings:

Fig. l is a side elevation of my de vice viewing the same from theinside portion;

Fig. 2 is a similar view showing the outside portion;

Fig. 3 is an enlarged section taken on the line 3-3 of Fig. 4, and

Fig. 4 is a bottom plan view of Fig. 3.

In the construction of my device I employ a curved member 5 whichterminates in a spherical portion 6. The member 5 and spherical portion6 are made hollow. Extending from the spherical portion 6 is a taperedmember 7 which is provided on its end with a rounded edge or bead 8. Themember 5 is provided on its inside face with an o ning 9 which permitsaccess of soun waves into the hollow portion. The member 5 isapproximately circular in cross section through a portion of its length,the portion containin the opening 9 being flattened so as to besustantially elliptic. The projection 7 is provided with a passageway 10which communicates with the interior of the spherical portion 6.

My device is used in the following manner :-The cylindrical portion 7 isinserted in the ear so that it extends in close roximit to the ear drumwhile the mem er 5 lits 1n the outer ear with the opening 9 lying closeagainst the head within the outer ear and being unexposed. By placingthis opening 9 against the head, any sudden 1nrush of air or increase ofair pressure due to violent sounds is prevented, and furthermore, theposition of this opening prevents dust or other foreign matter frombeing carried therein by the outside air.

My device is preferably made of metal, such as gold, silver or the like,and may, if found desirable, also be treated with radium. This has beenfound to be especially beneicial in some cases.

After my device has been placed in the ear, the air therein ispractically dormant, in other words, no air currents can enter and anyvibration set up is received by the outer ear and imparted to the airwithin my device and from there carried to the inner ear.

By my construction there are no sharp angles which would cause suddendeflection of the sound waves and consequently ne distortion of soundreaches the ear.

My device is intended to eliminate the use of head-phones, speakingtrumpets and other unsightly cumbersome devices, and when in use do notinconvenience the wearer and do not attract a great deal of attention tothe wearer as is the case with various other de* vices used for the samepurpose.

Having fully described my invention what I claim is l. An audiphonecomprising a hollow curved member having an opening in one side andadjacent one end, a hollow spherical portion formed integral with theother end of said member, and a hollow tapered member projecting fromsaid spherical portion, said tapered member and the opening in thecurved member being on the same side.

2. An audiphone comprising a curved member terminating at one end in asubstantially spherical shaped portion, a tapered member integral withand projecting from said spherical portion at right angles to the axisof the curved member, the curved member, spherical member and taperedmember being hollow and communicating with each other. and the curvedmember provided on one side with an opening communieating with theinterior of said member, said opening being arranged on the same side asthe tapered member so that when the device is in use, the opening willbe turned toward the head of the wearer and not be exposed.

3. An audiphone comprising two hollow portions communicating with andarranged at an angle to each other, one of said portions adapted to beinserted in the ear pastheethevportion with n closedend uid zith anunexpom4 Ao when the device is in use, between thepnl end and the firstmentioned member. 5 4. An audiphone com rising e hollow member closed atboth en ,Y ber secured at en angle to one side of said member and commwithfthe interior thereof, said tubular member adapted 1o whe inserted-in the eer 1 1 Q1 one of seid members rovided with an opening in itsside,'whio o ing is arranged tobe unexposedwhen t e device is in use.
